I've tried a number of search keywords and couldn't find anything relevant, so forgive me if I didn't use the right keywords.

Does anyone know where I can find info on producing custom sprays for Source? All my old ones from DOD come out blurry and basically unviewable in Source. Yet I can't find any guides on what are the proper dimensions, color palette, etc. for Source.

The source engine has the unique ability to import standard JPG pictures into the engine as a spray image - thus enabling you to use pretty much any image as a spray.

Unfortunatly, pictures above a certain size are reduced - to enable viewing.

Remember, that custom sprays are only as detailed as YOUR personal computer texture detail settings - so if your comp texture detail is on low, you will see a blurry spray image. However, other players that have they're texture detail on high, will see a better quality image.

Animated spray logos i know nothing about however - there are some tutorials here, but as i found out with custom xhairs - not many ppl actually know how to do much with source...
